Does America need the law of the jungle - the second amenemnt to the US Constitution?

A mentally deranged man can buy guns; and he shoots to kill 26 people, including 20 lovely little children, at an elementary school. And the President of the USA weeps. His administration and the US Congress remain essentially impotent spectators of this kind of horrible tragedies! One man can buy more than 30 high-powered guns; and he shoots to kill 58 people and injure more than 500 people in an outdoor concert. And the President of the USA is proud to be an American because of the professionalism of the hospital staff that treated the injured and of the victims that showed the bravery to help other fellow victims. But his administration and the US Congress remain essentially impotent spectators of this kind of horrible tragedies! The tragedies keep repeating!! Isn't it overdue for the USA to repeal the second amendment to its Constitution? In civilized human societies, shouldn't ordinary citizens get protection through laws and law enforces? Should they need private ownership of guns? Should guns be so easily available in this country?
Of course it is, but we have REPUBLICANS and they’re in the pocket of the NRA. They don’t care how many people get killed or maimed as long as nobody tries to take away their guns. That’s all that matters. They wouldn’t care if a hundred innocent people were killed every day. It would be worth every death and injury just as long as they can keep their guns and buy more.
